Though I have the same problem that is in this question, But I am facing another problem i.e, even / is not running in the browser and showing that this webpage is not available and this happens after I installed Heroku.

Cannot access github from terminal and not even from browser.

After diagnosis I get to know that this problem is related to my WiFi because when I try to open / in mobile using mobile data, It is opening but when I connect my mobile to WiFi then same problem i.e, this webpage is not available and when I use mobile data internet in my laptop I am able to access the site but when using WiFi this webpage is not available.

I am running Ubuntu(Linux), dual boot with Windows-7

  • 1 Run a basic diagnostic test on your WiFi. 'ping 8.8.8.8' -- if it works, you got a DNS problem. If not, you are not connected to the internet at all. Ping your router, and if there is no response, there is your problem. – Aroll605 Commented Dec 31, 2014 at 7:06

  • 1 This definately looks like a DNS issue, you can access sites via IP but not through the URL. Not programming related like someone else has already said.

This definately looks like a DNS issue, you can access sites via IP but not through the URL.

You need to configure your routers DNS settings, personally I would set them to Google's DNS servers

8.8.8.8 (primary)
8.8.4.4 (secondary)
